Have you wondered how information from physical devices in the real world gets communicated to Smartphone processors? Do you want to make informed design decisions about sampling frequencies and bit-width requirements for various kinds of sensors? Do you want to gain expertise to affect the real world with actuators such as stepper motors, LEDs and generate notifications?
In this course, you will learn to interface common sensors and actuators to the DragonBoard™ 410c hardware. You will then develop software to acquire sensory data, process the data and actuate stepper motors, LEDs, etc. for use in mobile-enabled products. Along the way, you’ll learn to apply both analog-to-digital and digital-to-analog conversion concepts.
Learning Goals: After completing this course, you will be able to:
1. Estimate sampling frequency and bit-width required for different sensors.
2. Program GPIOs (general purpose input/output pins) to enable communication between the DragonBoard 410c and common sensors.
3. Write data acquisition code for sensors such as passive and active infrared (IR) sensors, microphones, cameras, GPS, accelerometers, ultrasonic sensors, etc.
4. Write applications that process sensor data and take specific actions, such as stepper motors, LED matrices for digital signage and gaming, etc.

From the lesson

Bluetooth Remote

If you thought the IR remote module was fun, this will take your wireless control of the DragonBoard™ 410c to a whole new level. Here we will use multiple devices to communicate and control peripherals using Bluetooth. We will walk you through the steps we took in order to send and receive data through the Bluetooth modules on multiple devices. By the end of this module you will be able to control a variety of components (including GPIOs) on your DragonBoard™ 410c from other devices using close range Bluetooth connectivity. We are very excited to share this code with you, and we are even more excited to see all of the cool stuff you will all come up with when you are finished with this Module.
